FERRORESONANT BATTERY CHARGERS

C-CHARGER®CI SERIES

™

SINGLE-RATE FLOAT BATTERY CHARGERS

Safe to say, there’s no other float
charger built like a C-Charger from
Charles Industries. Rugged #304
grade stainless steel forms the sturdy
housing that withstands virtually all
environmental challenges; including
heat, humidity, vibration, and other
stress factors. The steel cover is
hinged to ease installation.

Electrically, the C-Charger is a
paragon of efficiency and simplicity.
It uses a ferroresonant transformer
with integral self-regulation. It has
been intelligently designed to be
completely devoid of any complicated
switching circuits that could possibly
burn out. There are no tubes nor
delicate electronics to fail or to cause
radio frequency interference (RFI). By
simplifying our design, Charles has

increased reliability without
sacrificing performance or usability.

Voltage output to the batteries
remains at a safe and constant DC
level from full load to no load, even
if AC power runs as high as 132
VAC or as low as 108 VAC. This
automatic voltage regulation
relieves strain on internal electrical
components and lengthens the
lifespan of the unit. All components
are designed to operate safely and
continuously in an ambient
temperature as high as 122º F.

CI Series Battery Chargers are
available in 12, 24 and 32 Volt
models and may be used with both
lead acid and nickel cadmium batery
banks.
